What are the differences between hosting, VPS, VDS, and dedicated servers?

Differences Between Hosting, VPS, VDS, and Dedicated Servers

Web hosting is the most affordable service for hosting simple websites. Users can upload their website’s source code to the hosting provider’s server via FTP and access a shared MySQL database. Typically, this service offers limited control over server settings, programming languages, and applications, making it difficult to diagnose issues without assistance from technical support.

VPS (Virtual Private Server) operates through virtualization based on the operating system. Common implementations include OpenVZ and FreeBSD Jail. Users enjoy a separate programming environment and superuser rights, but cannot change the kernel or OS family. Resource availability can vary based on the hosting provider’s policy.

VDS (Virtual Dedicated Server) offers a constant allocation of memory, disk space, and CPU cores with fixed resource allocation. Supported by hardware virtualization technologies like KVM, XEN, and VMWare, VDS allows the installation of any x86-compatible OS. This leads to enhanced data security and configuration possibilities, exemplified by our SSD VDS.

Both VDS and VPS are virtual solutions that host multiple virtual machines on a single physical server, each serving different user needs.

In contrast, a dedicated server (DS) is a physical machine with exclusive access to all resources such as bus bandwidth and memory. These servers are optimized for continuous operation under high load in our data centers, providing maximum performance and control to users, as detailed in our dedicated servers.

Analogy for Easy Understanding

• Web Hosting: A room in a student dormitory, where everyone shares amenities.
• VPS: An apartment share with separate rooms but communal kitchen.
• VDS: An apartment building with private space and shared walls.
• Dedicated Server: A spacious cottage with its own garden and barbecue.
